Common, interstitial nephritis, low potassium and high calcium
In addition, hemorrhagic fever with renal syndrome, diffuse cutaneous vascular horn tumors, acute renal failure, polyuria can cause increased urine output.
How to determine what kind of polyuria?
Chronic interstitial nephritis
Many of these patients with kidney disease have exposure to nephrotoxic drugs, urinary sediment will have a small amount of white blood cells. Proteinuria not much (protein qualitative 1+ the following quantitative 0.5g). And poor appetite, anemia, renal bone disease, no obvious edema and high blood pressure. Do B-will find two kidney shrink.
Hemorrhagic fever with renal syndrome
Hemorrhagic fever with renal syndrome is caused by the hantavirus, the daily urine output will be 3000ml
Diffuse cutaneous vascular
Diffuse skin vascular cutinoma is a genetic disease, the disease will have pain in the hands and feet.
Acute renal failure
Acute renal failure polyuria, urine output may reach 5000ml per day. This is like a judge, and creatinine will rise rapidly.
Hyperkalemia
Blood potassium concentration of 2.5 ~ 3.0mmol / L, there will be increased urine output phenomenon.
How to do more urine?
Interstitial nephritis caused by polyuria, the first need to control and remove the cause, such as the lifting of urinary tract obstruction and reflux, disable some of the anti-inflammatory drugs, aristolochic acid drugs, control of infection and other diseases. In addition, to maintain electrolyte balance, prevent dehydration, hypotension, correct anemia.
Hypokalemia caused by polyuria, potassium chloride can be added or potassium citrate
Hypercalcemia caused by polyuria, fluid replacement should be timely and promote urinary calcium excretion, bone calcification.
